The Game of Love by Jeanette Murray
Chris St. James is ready for normal. After walking away from her pro tennis career and a toxic relationship with a star hockey player, she's starting a new life as a teacher and tennis coach in a small town. Now all she needs is an average guy to share it with.
Brett Wallace is no average guy. Forced to retire from the NFL after an injury--and suddenly single after being dumped by his status-conscious wife--he's returned to his hometown to coach the varsity football team. Wary of women interested only in his celebrity, Brett finds Chris's indifference to his former career refreshing.
The last thing Chris needs is to get involved with another pro athlete, but she can't deny the sparks that fly between them. So she agrees to a purely physical, no-strings-attached affair. But the rules of the game change when she falls for him...
